Abstract

A patient support apparatus may include a base frame, lift arms, an intermediate frame, a deck support having three articulating sections, a brake system, various drive motors, actuators, and sensors, at least one power source, communication devices, and at least one controller, wherein the lift arms, articulating sections, drive motors, brake system, and actuators may be controlled from the at least one controller and in response to signals received by the various sensors, while storing data internally and/or sending data to a remote location.

Claims

1. A patient bed comprising:

a base frame;

a support frame system supported relative to said base frame and having a perimeter, and comprising a deck support having a top surface area and at least two chosen from a head section, a seat section, and a foot section, wherein at least one of said sections is movable relative to another of said sections of said deck support;

a control module having a housing, a motor, and a sensor;

an articulating support arm, said support arm pivotally coupled to said support frame system, said support arm being positionable at a plurality of locations around the perimeter of said support frame system, and said support arm adapted to support said control module;

a coupling device at a distal end of said support arm, wherein said coupling device is adapted to couple to said control module at said housing to permit three dimensional movement of said control module; and

wherein said motor and said sensor of said control module are configured to allow said control module to maintain a predetermined angle or position relative to a floor surface regardless of the angle of said deck support and any of said at least two chosen from said head section, said seat section, and said foot section relative to the floor surface.

2. The patient bed of claim 1, wherein said support arm is adapted to remain substantially stationary during movement of any of said sections of said deck support.

3. The patient bed of claim 1, wherein at least one of said sections of said deck support comprises at least one movable side pullout extension adapted to selectively widen or narrow the top surface area of the deck support, said at least one side pullout extension being movable between a retracted position and at least one extended position.

4. The patient bed according to claim 3, wherein said head section is pivotally connected to said seat section and said foot section is pivotally connected to said seat section opposite said head section.

5. The patient bed according to claim 3, wherein said foot section comprises a movable end pullout extension, said end pullout extension adapted to selectively lengthen or shorten the top surface area of the deck support, said end pullout extension being movable between a retracted position and at least one extended position.

6. The patient bed according to claim 3, wherein at least one chosen from said head section, said seat section, or said foot section comprises one or two side pullout extensions, each of said side pullout extensions located at an one of two opposite sides of a respective section, said side pullout extensions adapted to extend a distance out from a respective side of the respective section and to retract at least partially into the respective section.

7. The patient bed according to claim 3, wherein at least one of said head section, said seat section, or said foot section further comprises a latch adapted to releasably lock said at least one movable side pullout extension in the retracted position.

8. The patient bed according to claim 3, wherein said foot section further comprises a latch adapted to releasably lock said end pullout extension in the retracted position.

9. The patient bed according to claim 1, wherein said coupling device further comprises a pair of coupled link arms.

10. The patient bed of claim 1, wherein said support arm is adapted to support an IV pole.

11. The patient bed of claim 1, wherein said coupling device is adapted to accommodate a wire linking said control module to the bed.

12. A patient bed comprising:

a base frame;

a support frame system supported relative to said base frame and having a perimeter;

a control module having a housing, a motor, and a sensor;

an articulating support arm, said support arm adapted to mount to said support frame system, said support arm being positionable at a plurality of locations around the perimeter of said support frame system, and said support arm adapted to support said control module;

a coupling device at a distal end of said support arm, said coupling device being coupled to said control module at said housing;

a stopping mechanism at said coupling device, said stopping mechanism configured to permit variable positioning of the object, whereby said support arm is configured to be adjusted from a first of a plurality of positions by applying a manual force, and is configured to be subsequently stopped in a second of said plurality of positions by said stopping mechanism after removal of the application of the manual force;

wherein said support frame system comprises a deck support having a top surface area and at least two chosen from a head section, a seat section, and a foot section, wherein at least one of said sections is movable relative to another of said sections, and wherein said articulating support arm remains substantially stationary during movement of any of said sections; and

wherein said motor and said sensor of said control module are configured to allow said control module to maintain a predetermined angle or position relative to the floor surface regardless of the angle of said deck support and any of said at least two chosen from said head section, said seat section, and said foot section relative to the floor surface.
